A former assistant football coach at Franklin High School in Seattle has been arrested on suspicion of attempted rape of a child after he arranged to meet a police detective who'd sent him text messages posing as a 13-year-old girl.

Police also are seeking to have Omar P. Urrutia, 35, charged with communicating with a minor for immoral purposes, said Kent Assistant Police Chief Pat Lowery.

Urrutia told detectives he was a coach at the school and also a coach for a semipro female football team, according to court documents.

The case began when a Kent woman called police on Oct. 27, concerned about suggestive text messages between her 13-year-old daughter and an adult male. Posing as her daughter, the woman corresponded with the man, whose messages included a mention of oral sex.

A Kent police detective continued the ruse, posing as a fictional, 13-year-old friend of the first girl. Probable-cause documents filed with King County District Court allege Urrutia asked questions like: "How old r u? U ever been with an older guy?"

Seattle Public Schools spokeswoman Teresa Wippel said Urrutia was a contract employee for the football season, which ended before the alleged incidents took place. After hearing of his arrest, the school notified Urrutia that he was not to have any contact with students and not to return to the campus.

Parents, football players and cheerleaders were notified of the allegations against the former coach, and told to notify Kent police if they knew of any other incidents.

Urrutia identified himself by name in some of the messages and provided his address, court records say. He arranged to meet what he thought were two 13-year-old girls at the Renton Transit Center on Oct. 29. Police arrested him there. Court documents say Urrutia told officers he was "just flirting." He also said his judgment was cloudy and that he needed help and counseling.
